Configuring the Encryption Content Filter
After you create an encryption profile, you need to create an outgoing content
filter that determines which email messages should be encrypted. The content
filter scans outgoing email and determines if the message matches the conditions
specified. Once the content filter determines a message matches the condition, the
Cisco IronPort Email Security appliance encrypts the message and sends the
generated key to the key server. It uses settings specified in the encryption profile
to determine the key server to use and other encryption settings.
